Hey lets revive this discussion
My monster 821 came with the diablo rosso II's they are ok but nothing spectacular, grip is mediocre to good when the road is dry and conditions warm. Cold & wet circumstances do not bring the best out of the tire
I had signs of wear very soon, the rear tire started becoming flatter in the middle close to the 5000 km and at ±8000 km (±5 k miles) I was already in the lookout for new tires finally replaced the rear tire at 10000km (6.2 k miles). The front was replaced (i think) at 12000 km (7.2 k miles).
Next was the Michelin pilot road 4 front and rear. Lasted much longer and provided better grip in the wet but did not disappoint on the dry warm conditions either. A good all rounder but produced more noise (as expected) and did not come at 60/180 but 55/180, this messed up with the DTC and mileage. Changed the rear one after 16000 km (±10 k miles) while the front tire is still holding on ok after 19000 km (11.8 k miles)
Last update on the tire front replaced the rear tire to the Diablo Rosso III, after almost 5000 km (3 k miles) I am very impressed retains its shape well, very good grip in the dry - not lots of experience with this one on wet tarmac but lost the back a couple of times slightly in low speed turns around town in the wet, nothing dramatic though.
So far the diablo rosso III has performed the best at least for the rear and I am glad that the wear is even which allows for a good riding experience.
